The prevalence of both domestic violence (DV) and HIV among Kenyan women is known to be high, but the relationship between them is unknown. Nationally representative cross-sectional data from married and formerly married (MFM) women responding to the Kenya Demographic and Health Survey 2008/2009 were analyzed adjusting for complex survey design. Multivariable logistic regressions were used to assess the covariate-adjusted associations between HIV serostatus and any reported DV as well as

four constituent DV measures: physical, emotional, sexual, and aggravated bodily harm, adjusting for covariates entered into each model using a forward stepwise selection process. Covariates of a priori interest included those representing marriage history, risky sexual behavior, substance use, perceived HIV risk, and sociodemographic characteristics. The prevalence of HIV among MFM women was 10.7% (any DV: 13.1%, no DV: 8.6%); overall prevalence of DV was 43.4%. Among all DV measures, only physical DV was associated with HIV (11.9%; adjusted odds ratio: 2.01, p < .05). Efforts by the government and women’s groups to monitor and improve policies to reduce DV, such as the Sexual Offences Act of 2006, are urgently needed to curb HIV, as are policies that seek to provide DV counseling and treatment to MFM women. In Kenya, as in much of Sub-Saharan Africa (SSA), women are disproportionately affected by both HIV (UNAIDS, 2012) and domestic violence (Goo & Harlow, 2012; Jewkes, 2002; Kishor & Johnson, 2004; Koenig et al., 2003; Wanyoni & Lumumba, 2010). Among Kenyans aged 15 to 49 years, 8% of women compared with 4% of men report HIV infection (Kenya National Bureau of Statistics [KNBS] & ICF Macro, 2010), and higher prevalence of domestic violence among Kenyan women has been previously reported (Abuya, Onsomu, Moore, & Piper, 2012; Fonck, Leye, Kidula, Ndinya-Achola, & Temmerman, 2005; Goo & Harlow, 2012; Kishor & Johnson, 2004; Wanyoni & Lumumba, 2010). Despite the high prevalence of both DV and HIV among Kenyan women, the relationship between DV and HIV remains unclear. Although several investigators have observed an association between DV and HIV (Dude, 2011; Jewkes, Dunkle, Nduna, & Shai, 2010; Shi, Kouyoumdjian, & Dushoff, 2013; Silverman, Decker, Saggurti, Balaiah, & Raj, 2008), in the largest study on this topic—which incorporated data from 10 developing countries including Kenya—an association was not observed (Harling, Msisha, & Subramanian, 2010). All of these studies, however, are subject to important methodology and context limitations that may in part explain the discrepant findings. In the current study, we have addressed many of the limitations found in the existing literature in order to more accurately assess the relationship between DV and HIV infection among Kenyan women. An accurate understanding of the relationship between DV and HIV is paramount to the development of interventions to address these deeply rooted societal problems, which take a particularly heavy toll among women in Kenya and women throughout SSA. Intimate partner violence (IPV), which includes DV, is the most common form of gender-based violence (Garc´ıa-Moreno, Jansen, Ellsberg, Heise, & Watts, 2006). It is defined as “the range of sexually, psychologically and physically coercive acts used against adult and adolescent women by current

or former male intimate partners” (World Health Organization [WHO], 1997, p. 5). Experts estimate that in African countries, 25%–48% of women will suffer abuse at one point in their lives (Goo & Harlow, 2012; Jewkes, 2002; Kishor & Johnson, 2004; Koenig et al., 2003; Wanyoni & Lumumba, 2010). Its prevalence in Kenya is established (Abuya et al., 2012; Fonck et al., 2005; Goo & Harlow, 2012; Kishor & Johnson, 2004; Wanyoni & Lumumba, 2010), and Abuya and colleagues (2012) showed that physical (42%) and sexual (14%) violence toward Kenyan women fell in the middle range of multicountry estimates reported by the WHO, 14%–61% and 6%–59%, respectively (WHO, 2005). Emotional violence is also rampant (Abuya et al., 2012; Fonck et al., 2005; Goo & Harlow, 2012; Kimuna & Djamba, 2008). Physical and sexual violence, including sexual assault within marriage, increase transmission of the virus as tears and lacerations to the vaginal canal enable its invasion of the vaginal epithelia (Garc´ıa-Moreno & Watts, 2000; Kishor & Johnson, 2004; van der Straten et al., 1998; Wittenberg, Joshi, Thomas, & McCloskey, 2007). Socially, the threat of IPV often impedes open communication regarding disease risk. Women refrain from discussing their husband’s risky behaviors, such as having extramarital partners or frequenting sex workers (Karamagi, Tumwine, Tylleskar, & Heggenhougen, 2006; Lary, Maman, Katebalila, McCauley, & Mbwambo, 2004; Lasee & Becker, 1997), and avoid disclosing their own HIV serostatus in fear of accusations of infidelity, abandonment, discrimination, physical and emotional violence, and disruption of family relationships (Antelman et al. 2001; Gaillard et al., 2002; Medley, Garc´ıa-Moreno, McGill, & Maman, 2004). Women reporting physical and emotional IPV also reported impaired emotional and social functioning, including depression, helplessness, resignation, and isolation from friends, family, and religious groups (Dietz et al., 1997; Wittenberg et al., 2007). Further, IPV has been shown to affect a woman’s participation in household decision making, including decisions about her own health, for example, whether to seek skilled health care (Antelman et al., 2001; Dietz et al., 1997; Dunkle et al., 2004; Fonck et al., 2005; Gaillard et al., 2002; Goo & Harlow, 2012; Izugbara & Ngilangwa, 2010; Malhotra, Schuler, & Boender, 2002; Maman et al., 2002; Medley et al., 2004; WHO, 2005). IPV is also associated with increased HIV risk in women because men who abuse their wives exhibit other risky behaviors, including drug abuse and alcohol misuse (Gielen, McDonnell, & O’Campo, 2002; Karamagi et al., 2006; Zablotska et al., 2009), multiple sexual partners (Martin et al., 1999; Onsomu et al., 2013), and lack of condom use (Gielen et al., 2002; Karamagi et al., 2006). Patriarchal cultural pressures that encourage men toward early sexual initiation and multiple sexual partners prior to marriage are also associated with increased incidence of infection (Abuya et al., 2012; Dunkle et al., 2006; Lary et al., 2004; Silverman et al., 2008). These factors are

exacerbated by dominant and controlling men who manipulate their partners (Wang & Rowley, 2007; Wingood & DiClemente, 1998) and increase women’s risk of contracting HIV (Decker et al., 2008; Dude, 2011; Silverman et al., 2008). One of the nine priority areas in the UNAIDS Outcome Framework for 2009–2011 (2009) is to end violence against girls and women, especially because it increases their susceptibility to HIV infection (Andersson, Cockcroft, & Shea, 2008; Campbell et al., 2008; Garc´ıa-Moreno & Watts, 2000; Martin & Curtis, 2004; WHO, 2004). Although prevalence varies, many countries acknowledge the association between violence and HIV susceptibility among women. For instance, in eastern and southern Africa, IPV is associated with high risk of HIV infection (Abuya et al., 2012; Dunkle et al., 2004; Fonck et al., 2005; Jewkes, Levin, & Penn-Kekana, 2003; Jewkes et al., 2010; Karamagi et al., 2006; Kiarie et al., 2006; Lary et al. 2004; Maman et al., 2002; van der Straten et al., 1998). Additionally, qualitative studies have highlighted the links among HIV/AIDS, gender inequities, and DV as an outcome of the patriarchal nature of African societies and notions of masculinity that emphasize male strength and toughness and perpetuate control of women (Coovadia, Jewkes, Barron, Sanders, & McIntyre, 2009; Go et al., 2003; Jewkes et al., 2010). Such norms have led some women to accept and tolerate male dominance to the extent of rationalizing IPV (Izugbara & Ngilangwa, 2010; Lawoko, 2008). For example, researchers found that traditional practices in some rural Kenyan communities could predispose women to higher risk of physical violence (Abuya et al., 2012). The prevalence of violence impedes women’s ability to negotiate for safe sex, which often results in low condom use (Abuya et al., 2012; Andersson et al., 2008; Campbell et al., 2008; Garc´ıa-Moreno & Watts, 2000; Go et al., 2003; Karamagi et al., 2006; WHO, 2004). Although research has shown that women are at greater risk of HIV infection, particularly in areas where HIV infection is high, prevention messages largely continue to focus on HIV testing, male condom use (Go et al., 2003), treatment of sexually transmitted diseases, and, most recently, male circumcision and antiretroviral treatment. Notably, interventions have not focused on gender-specific problems nor benefited vulnerable women (Christofides & Jewkes, 2010; Wawer et al., 2009). From the foregoing arguments, research continues to show that genderbased violence, usually an outcome of male dominance, results in high-risk sexual behavior (Dunkle et al., 2004; Gilbert, El-Bassel, Schilling, Wada, & Bennet, 2000; Jewkes et al., 2003, 2006; Wingood & DiClemente, 1998; Zablotska et al., 2009). Women who experience violence in highly unequal relationships have greater chances of contracting HIV (Decker et al., 2008; Dude, 2011; Jewkes & Morrell, 2010; Karamagi et al., 2006; Silverman et al., 2008). Nonetheless, scholars examining HIV and IPV among women in 10 developing countries, including Kenya, found no association (Harling et al.,

2010). In the current study, we provide further evidence about the association between DV and HIV serostatus among married and formerly married (MFM) women in Kenya and improve on previous estimates by controlling for possible confounders.

Data Source Our cross-sectional study used a population-based national sample, the 2008/2009 Kenya Demographic and Health Survey (KDHS, 2008/09), with data collected between November 2008 and February 2009. This survey was the second to collect information on HIV serostatus, following the KDHS2003 (Central Bureau of Statistics [Kenya], Ministry of Health [Kenya], and ORC Macro, 2004). Data were limited to a subsample of women aged 15–49 from a merged dataset that considered those who were married (n = 5,041) or formerly married (n = 863); of these women, 4,906 (83.1%) responded to questions about DV. Among these married and formerly married women, 2,669 of them agreed to be tested for HIV; among them, 442 did not respond to DV questions and were excluded from the final analyses. The total sample of 2,227 (83.4%) were tested for HIV and responded to DV questions, which allowed us to estimate the association between DV and HIV serostatus. Study data were weighted to account for a clustering effect to eliminate over- and underestimation in the standard errors (StataCorp, 2013).

Survey Measures HIV serostatus. National Public Health Laboratory Services personnel were involved in the collection of dried blood spot (DBS) samples, voluntary counseling and testing, and laboratory testing for HIV. All positive samples and a random selection of negative samples (10%) were subjected to further testing at the HIV laboratory of the Kenya Medical Research Institute (KEMRI) using the same procedure. Further analysis by polymerase chain reaction of the deoxyribonucleic acid (DNA) in the same laboratory on 30 discrepant samples were conducted. See KNBS and ICF Macro (2010, pp. 9–10) for a complete description of the HIV procedures and testing. All DBS testing was done in early June 2009. Domestic violence. Evaluation of DV among married and formerly married women was based on a modified Conflict Tactics Scale (CTS) used in the KDHS-2008/09, which has proven effective in measuring DV across cultures (Strauss, 1990, cited in KNBS & ICF Macro, 2010). Questions were asked to evaluate abuse and coded as no, “0,” or yes, “1.” Common factor analysis was used to group and identify patterns from the various questions while maintaining the needed information with minimal loss.

The factors that mostly explained/measured certain themes based on rotated factor loadings were retained and named based on the overall theme represented by their constituent items; these themes were named and used for analyses as the study exposures. Dichotomous variables generated from the retained factors explained most of the total variance (40%–62%) for each of the four themes identified: (a) physical violence (push you, shake you, or throw something at you?; slap you?; twist your arm or pull your hair?; punch you with his fist or with something that could hurt you?; kick you or drag you or beat you up?); (b) emotional violence (say or do something to humiliate you in front of others?; threaten to hurt or harm you or someone close to you?; insult you or make you feel bad about yourself?); (c) sexual violence (physically forced you to have sexual intercourse even when you did not want to?; force you to perform any sexual acts you did not want to?); and (d) violence with aggravated bodily harm (AGBH; try to choke you or burn you on purpose?; threaten to attack you with a knife, gun, or any other weapon?). A fifth theme was generated from all of the four variables and named “all forms of violence.” All themes were coded as “0” if respondents indicated that they did not experience violence, and “1” if they did. Weights and correlations between each variable (factor loading) were determined at
